Time's running out to catch "August: Osage County," which is getting a killer staging at the Sheldon Vexler Theatre. The show - in which a dysfunctional family gathers in the wake of the patriarch's suicide to figure out, among other things, what to do with the difficult, pill-addicted, cancer-afflicted matriarch - is funny and powerful and an absolute must-see. Final performances are at 7:30 p.m. Thursday, 8 p.m. Saturday and 2:30 p.m. Sunday at the Vex, inside the Barshop Jewish Community Center, 12500 NW Military Highway. Call 210-302-6835 for reservations.
